ranged-num is a crate for representing a single number that is in some compile-time known range of values. You can use any underlying numeric type to hold the actual value. The main type to look at is Ranged.

Example:

use typenum::{N2, P3, P4};
use ranged_num::Ranged;

let ranged = Ranged::<N2, P4, isize>::new::<P3>();
assert_eq!(ranged.value(), 3);
